Material not applied properly
Don't know if this will work, but here's something you can try:
first remove the texture, go into object mode, select the jeans, and apply the scale using ctrl+a. 
Then go into edit mode with your jeans, use "a" to select everything, and hit u -> UV unwrap. I think this will generate a different set of faces.
Finally add the texture back on using lily's surface scraper.
